Root Exposure
Root exposure means the root of a tooth is no longer fully covered by gum tissue. Unlike the crown of a tooth, which is protected by enamel, the root surface is softer and more sensitive. Exposure often follows gum recession, and it can make a tooth very sensitive to cold, heat, or sweet foods, and more vulnerable to decay at the gum line.

What Root Exposure involves
A dentist will check how much root is exposed, whether decay is present, and what caused the gum to pull back. Care focuses on protecting the exposed root, treating any gum disease, and reducing sensitivity. In some cases, a dentist may discuss covering the root, depending on the tooth and the extent of exposure.

Frequently asked questions about Root Exposure
Is root exposure the same as gum recession?
They are closely linked. Recession is the gum pulling back; root exposure is the result, when the root itself becomes visible and sensitive.
Why is an exposed root so sensitive?
The root is not covered by enamel, so temperature and touch reach the inner tooth more easily than on the crown.
Can an exposed root be covered again?
Sometimes a dentist can discuss covering the root, depending on the tooth. Care first focuses on stopping further recession.
